The following larvae (with the exception of the one first described) 

 have the usual On-ysovielid form of which the well-known Colorado 

 Potato Beetle may be taken as a type. In Chrysomela pallida, Say, the 

 body is more elongate, approaching the Coccifiellidce somewhat in form. 

 \\"\t\\ the exception of Lciiia rollaris, Say. which forms a sort of cocoon 

 among the leaves, they all enter the earth to pupate. A few of the fol- 

 lowing larvi"e have been described bv various nuthnrs, and nre introduced 

 here merely for comparison.

 and roughened ; the sutures of the segments and the venter some-

 from the pupa July 25. Two were taken /// coit// June 19 ; the male was"
